<p dir="auto">I have a library that provides <code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0 0.4em" bgcolor="#F7F7F7">DEF-UNIMPLEMENTED</code> as a macro for defining stub functions. When you compile a file with unimplemented functions, you get a warning of the type <code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0 0.4em" bgcolor="#F7F7F7">FOO:UNIMPLEMENTED-STUB</code> in my library <code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0 0.4em" bgcolor="#F7F7F7">FOO</code>.</p>
<p dir="auto">I'd like to put in an asdf system definition a file spec something like this:</p>
<pre style="background-color:#F7F7F7; border-radius:5px 5px 5px 5px; margin-left:15px; margin-right:15px; max-width:90vw; overflow-x:auto; padding:5px" bgcolor="#F7F7F7"><code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0" bgcolor="#F7F7F7">(:file "file-with-stubs"
:method (:around (o c)
(handler-bind ((foo:unimplemented-stub
#'(lambda (c)
(print c)
(muffle-warning c))
(call-next-method)))
</code></pre>
<p dir="auto">but, of course, the package <code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0 0.4em" bgcolor="#F7F7F7">foo</code> doesn't exist when this is read (although I could put <code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0 0.4em" bgcolor="#F7F7F7">(asdf:load-system "foo")</code> upstream of the enclosing defsystem).</p>
<p dir="auto">This isn't a case that's nicely consistent with Faré's hack for translating strings or keyword symbols, nor does it seem easy to use <code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0 0.4em" bgcolor="#F7F7F7">find-symbol</code> for this purpose.</p>
<p dir="auto">Thoughts?</p>
